为使风轮测涡技术能定量使用,采用了有效的设计和工艺,使风轮轴摩擦扭矩的影响降到最低,方便了标定;提出了测量结果处理的新技术,使尺寸相对较大的风轮也可测定梯度变化剧烈的涡场。这两个措施的结合使风轮测量技术定量化成为可能。测量的结果表明,风轮测涡技术确可成为一种迅速定量测量集中流向涡的有效方法。 In order to make the rotor vortex measurement technology can be used quantitatively, an effective design and process are adopted to minimize the influence of the friction torque of the rotor shaft, which is convenient for calibration. A new technology of measurement result processing is proposed to make the wind of relatively large size Wheels can also be measured gradient drastic vortex field. The combination of these two measures makes it possible to quantify wind turbine measurement techniques. The measurement results show that the rotor vortex measurement technique can indeed become an effective method for rapid and quantitative measurement of concentrated flow vortices.
